Backed by a 15-year agreement, Sunsure will supply power to NVVN with Uttar Pradesh Power Corporation being the end procurer. Under the agreement, Sunsure will set up a stand-alone Battery Energy Storage System (BESS) under the Build-Own-Operate (BOO) model at Garautha Substation (400/220 kV) in Jhansi, Uttar Pradesh.
The project marks Sunsure’s first long-term power supply agreement through BESS. Through the agreement, the company will deliver four hours of on-demand power between 6 PM and 10 AM, giving Uttar Pradesh Power Corporation the flexibility to source clean energy at peak demand hours (evening or morning) at competitive and long-term tariffs.
This brings a historic shift in India’s energy storage ecosystem as it is a first-of-its-kind BESS agreement where instead of fixed monthly rates, billing is based on fixed tariff (INR/kWh) of discharged energy.
Commenting on the agreement, Shashank Sharma, Founder, Chairman and CEO, Sunsure Energy, said, “Round-the-clock renewable energy is the need of the modern, growing India. The next generation of clean energy infrastructure will not be the one that works only when the sun shines or when the wind blows—but one that works when India needs it the most. At Sunsure, we’ve spent the last 24 months quietly building capabilities for that future. We've moved from pure-solar offerings to hybrid systems with BESS, enabling C&I customers to access renewable energy even during peak hours, while displacing more fossil energy from their energy mix.”
He further added, “On the utility side, our evolution is clear–from winning SECI’s pure solar bids to SJVN’s advanced hybrid tenders, and now, NVVN’s first-of-its-kind BESS deployment in the country. We’ve consistently moved up the technology curve, while preserving our returns. This shift is India’s power move in realising the dream of Atmanirbhar Bharat and fulfilling India’s goal of 500 GW of non-fossil generation capacity by 2030 and we are glad to be a part of it.”
